Grok API relay services 26 in total

Far fewer services support Grok than the families above — a relatively niche category with genuine demand. The narrow coverage comes from a limited number of upstream channels, which means only a handful of services can supply it reliably.

A small field cuts two ways. The upside is that choosing is simple; the downside is that unit prices are usually less competitive than other families — without much competition there is little room to negotiate. So the question here is availability rather than cheapness.

With so few options, a more conservative approach makes sense: test on a small amount first, confirm that calls are reliable before committing more, and keep a backup channel configured so you are not depending on a single provider.

• Most stable：Highest current uptime. Where samples are thin we show the public-dataset baseline instead, and the detail page states the source.
• Fastest：Home-page response time from the most recent probe. A single measurement is noisy, so treat it as a range rather than an absolute.
• Broadest model coverage：This uses the model count our endpoint probe actually detected, not the support list the service advertises — the two are measured differently, and the advertised figure is usually the more optimistic one.

Why do so few services support Grok?

Mainly because upstream channels are limited. Compared with mature ecosystems like GPT and Claude, there are noticeably fewer ways to connect to Grok, so fewer services can supply it reliably. It also means there is little point comparing prices aggressively — there is not much to choose from.

How stable is Grok through relays?

Overall uptime figures are on our comparison board. With so few services available, treat the stability tier as the main criterion rather than the unit price alone.

How do I check whether a service really offers Grok?

Request /v1/models and look for the matching model identifier. Our probe records what each service actually returns, which you can verify on its detail page.
